As part of my ongoing project of compiling and analyzing Scientology's statistics, I am collecting statistics from Advance magazine, the magazine of the Church of Scientology's Advanced Organization of Los Angeles.

Many, many people have contributed to the statistics project by sending in tallies, completions lists, or old magazines. The contribution page tells more about how you can help. I am very interested in receiving copies of any and all issues of
Advance, even those I have already. I trade duplicates with other
collectors so we can have robust collections spread out around the
world. I thank all those who have contributed so far!

I would like to extend special thanks to Cerridwen, who has transcribed so many completions lists and has been such a tireless collaborator on this project.
